Always the big question, how many lights on one breaker
I’m ask so many times how many outlets and or lights can I put on a 15 amp or 20 amp breaker. Well NEC code does not have it listed that way. By rule of thumb you would stick with 8 to 10 outlets and or lights per breaker. Now this is of course they are 120 volts 60mhz (USA or Canada).
Kitchen But let’s think of a kitchen or dining room. Just the name kitchen tells says “Countertop Micro, blender, toaster, toaster oven” And that’s just my house. Turn all those on at one and BAM You are over and the breaker will trip. That’s why code with kitchens is very different now. For a kitchen it’s 20amp and something like two outlets per breaker and no more than four feet apart of counter space. And any counter that is more than two feet wide needs an outlet. And all countertop outlets must be GFCI protected.
Garage Now in a garage code states that you only need one GFCI protected outlet. Now that’s just dumb and cheap to install one outlet in a garage anyway. But hey each to their own right.
Bathrooms Bathrooms must also have one GFCI outlet (20 amp)
So let’s say you’re wiring a simple bedroom. My rule of thumb and code is. An outlet within six feet either direction of the bedroom door and within 10 feet from there all around the room. So plan carefully when you get to the closets. Some simple planning and you’ll be fine.
Yes while wiring a bedroom you can to it the easy way and just come off of an outlet for the light. But remember if you trip the breaker in one of those outlets you lose the light as well. So placing lights a lot of the bedroom lights on its own breaker is way better. If you do it will make adding a transfer switch for a generator better for you in the future. Why ? Simple, then that way you’ll easy access to the lighting only for your bedrooms without overloading the generator. See that’s why, simple yeah !
That’s how I wire wired my house. And when we lost power during hurricane Sandy we had all the lights in the house working on a generator. But that’s another story altogether.
